OVE N FOR DRYING FRUIT.

SPECIFICATION forming part of Letters Patent No. 232,033, datedSeptember '7, 1880.

Application filed July 6, 1880.

To all whom it may concern:-

Be it known that I, GEORGE W. HOLMES, of Council Bluffs, in the countyof Pottawattamie, and in the State of Iowa, have invented certain newand useful Improvements in Ovens for Drying Fruit and for otherPurposes; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to theaccoi'npanyingdrawings, and to the letters of reference marked thereon, making a partof this specification.

This invention relates to certain improvements in ovens for drying fruitand for other purposes, and it has for its object to provide a portableapparatus which can be employed in connection with any ordinary stove orheater and by means of which the fruit can he subjected to the action ofa regulated heat, as more fully hereinafter specified. These objects Iattain by the apparatus illustrated in the accompanying drawings, inwhich Figure 1 represents a perspective view of my improved drier,showing the door thereof partly open; and Fig. 2, a longitudinalvertical section of my improved drier, showing the method of ventilatingthe drying chamber thereof.

The letter A indicates a rectangular box, formed with double walls B,except at the forward end, which is open. The bottom of said box isdepressed, as ind'eated by the letter C, so as to set in the opening atthe top of a stove or other heater, and the top of said box is providedwith a tube, I), through which the space between the double walls may beproperly charged with water and whereby the steam generated in saidspace may escape.

At the front of the drier, at each side of the same, are providedgrooved guides or ways E for a sliding door, E, which are provided withopenings G, by means of which communication between the dryingchamber Hand the external air may be established.

The exterior wall of the door, at each side of the openin gtll6I'Bill,IS provided with grooved (Mo dcl.)

guides or ways I, between which is adapted to slide a valve or damper,K, having an aperture, L, which may be brought opposite the openings inthe walls of the door, inorder to establish communication through saidopenings between the drying-chamber and the external air.

The interior of the drying-chamber, on opposite sides, is provided withhorizontal longitudinal flanges M, for supporting the shelves N, uponwhich the fruit to be dried is placed.

The operation of my invention will be readily understood in connectionwith the above description, and is as follows: The vessel or box isplaced upon a stove or other heater, with the depression at the bottomsetting in the aperture at .the top thereof. The space between thedouble walls is filled with water, and when heat is applied it istransmitted by means of the water to the drying-chamber containing thefruit. By means of the sliding valve in the door of the apparatus theheat of the drying-chamber maybe regulated by opening the valve to agreater or less extent, as may be required.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

An oven for drying fruit, consisting of a rectangular box constructedwith double walls, except at one end, and with a depression at thebottom to set in the opening of a stove, the said box being providedwith horizontal flanges on the inside to support a series of trays, andwith a sliding door having a sliding valve adapted to be operated toestablish communication between the interior of the oven and the openair, substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of June, 1880.
